One of the biggest advantages of the CSF Radiator over the OE Unit is the Triple Pass design. The internal routing of the radiator forces the coolant to flow through the core three times (see diagram below), maximizing heat dissipation and resulting in lower coolant temperatures. This type of configuration ensures more even heat dissipation, reducing hotspots and promoting more consistent cooling.
The Focus RS was very well engineered and performed admirably out of the box. However, a few upgrades can quickly lead to heat issues, especially on the track or in hot climates. An upgraded radiator from CSF is the perfect solution.
Fits: 2016-2018 Ford Focus
